HOW THE MACHINE WORKS
BRUSH INFORMATION
For best results, use the correct brush type for the
cleaning application.
NOTE: The amount and type of soilage play an
important role in determining the type of brushes
to use. Contact a Tennant representative for
specific recommendations.
Polypropylene Sand Wedge Main Brush −
Recommended for heavy accumulation of sand
and other fine particles.
Polypropylene Window Main Brush −
Recommended for light litter, especially on
smooth floors.
The steering wheel controls the direction of
machine travel. The directional pedal controls the
speed and forward/reverse direction. The brake
pedal slows and stops the machine.
The side brush sweeps debris into the path of the
main brush. The main brush sweeps debris from
the floor into the hopper. The vacuum system
pulls dust and air through the hopper and the dust
control system.
When sweeping is finished, shake the dust filter
and empty the hopper.
Polypropylene 8-double row Main Brush −
Recommended for general sweeping applications.
Polypropylene and Wire 8-double row Main
Brush − Recommended for general sweeping and
slightly impacted debris.
Polyester 8-double row Main Brush −
Recommended for general sweeping, especially
on rough or irregular surfaces. Nylon has a long
wear life.
Polyester Full Fill Main Brush − Recommended
for accumulation of sand and other fine particles.
Nylon has a long wear life.
Natural Fiber 8-double row Main Brush −
Recommended for accumulation of sand and
other very fine particles.
Polypropylene Side Brush − Recommended for
general sweeping of light to medium debris.
Nylon Side Brush − Recommended for general
sweeping of rough or irregular surfaces. Nylon
has a long wear life.
Flat Wire Side Brush − Recommended for
outdoor curb-side sweeping where dirt is heavy or
compacted.

OPERATION
WHILE OPERATING THE MACHINE
Pick up oversized debris before sweeping. Pick
up wire, string, twine, large pieces of wood, or any
other debris that could become wrapped around
or tangled in the brushes.
NOTE: Debris can be placed in the hopper
through the hopper access door on the front of
the hopper.
Drive as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
machine. Overlap the sweep paths by several
centimeters (a few inches).
Avoid turning the steering wheel too sharply when
the machine is in motion. The machine is very
responsive to the movement of the steering wheel.
Avoid sudden turns, except in emergencies.
Adjust the machine speed and brush pressure.
Use the lowest brush pressure for best
performance.
Keep the machine moving to prevent damaging
floor finishes.
If poor cleaning performance is observed, stop
cleaning and refer to MACHINE
TROUBLESHOOTING in this manual.
Perform the Daily Maintenance Procedures after
each use (see MACHINE MAINTENANCE in this
manual).
Drive the machine slowly on inclines. Use the
brake pedal to control machine speed on
descending inclines. Sweep with the machine up
inclines rather than down inclines.
FOR SAFETY: When using machine, go slowly
on inclines and slippery surfaces. Do not
sweep on ramp inclines that exceed 14%
grade or transport (GVWR) on ramp inclines
that exceed 17.6% grade.
Do not operate machine in areas where the
ambient temperature is above 43_ C (110_ F). Do
not operate sweeping functions in areas where
the ambient temperature is below freezing 0_ C
(32_ F).

Contact appropriate personnel if a leak is
discovered.
ATTENTION: Only use TENNANT supplied
hydraulic hoses or equivalent rated hydraulic
hoses.
ATTENTION! Hydraulic components depend
on system hydraulic fluid for internal
lubrication. Malfunctions, accelerated wear,
and damage will result if dirt or other
contaminants enter the hydraulic system.

WARNING: Moving belt and fan. Keep
away.
VALVE CLEARANCE
Check and adjust the valve clearance to 0.145 to
0.185 mm (0.0057 to 0.0072 in) while the engine
is cold after every 800 hours of operation.
FUEL FILTER
The fuel filter traps fuel contaminants. The filter is

MAINTENANCE
FUEL LINES
PRIMING THE FUEL SYSTEM
Check the fuel lines every 50 hours of operation.
If the clamp band is loose, apply oil to the screw
of the band and securely tighten the band.
Typical diesel fuel systems require priming to
remove pockets of air from the fuel lines and fuel
components. This is usually required after running
out of fuel, changing fuel filter elements or
repairing a fuel system component. Air in the fuel
prevents smooth engine operation.
This fuel system however is self-priming. The
return line comes from the top of the injector that
allows the air to escape through the return line.
VACUUM FAN BELT
Check the vacuum fan belt tension and wear after
every 200 hours of operation. The correct tension
is when the belt deflects 4 mm (0.16 in) from a
force of 0.7 kg (1.5 lb) at belt midpoint.
The rubber fuel lines can become worn−out
whether the engine has been used much or not.
Replace the fuel lines and clamp bands every two
years.
FOR SAFETY: When servicing machine, keep
flames and sparks away from fuel system
service area. Keep area well ventilated.
BATTERY
Clean and tighten the battery connections after
the first 50 hours of operation and after every 800
hours after that. Do not remove the vent plugs
from the battery or add water to the battery.
If the fuel lines and clamp bands are found worn
or damaged before two years’ time; replace or
repair them at once. Bleed the fuel system after
replacement of any fuel lines, see PRIMING THE
FUEL SYSTEM. When the fuel lines are not
installed, plug both ends with clean cloth or paper
to prevent dirt from entering the lines. Dirt in the
lines can cause fuel injection pump malfunction.
FOR SAFETY: When servicing machine, avoid
contact with battery acid.
